Pictures:

First is the lever end of the air bleed carb, showing one of the two ends of the clip holding the barrel tightly into the carb.

Second is the older TN with the metal throttle lever, starting point of the LS adjuster is flush with the surface of the needle.

Third is the later TN with the plastic lever. Starting point for the LS is about 1/32 below the surface.

This starting point on the TN carbs will be too rich for normal running, but it will run at full speed and idle, usually it will stumble on transition until it's leaned from that point.

Peak the HS, then check transition, leaning the LS a little at a time until it comes off idle well, then go a little more and recheck. You will start getting good transition while it's still rich, you can leave it there if you wish but the fuel burn rate will be high. Keep going lean until it doesn
t come on throttle crisply, then go back rich until it does.

All the time you're doing this keep rechecking the HS setting, the two will interact. After the LS is set, then go back to the HS and richen it to get your 200-300 rpm rich setting on the top end.
